摘　　要：为了探究油茶林间种花生模式的可行性,在油茶种植基地进行了油茶间种花生试验,通过林间调查法和室内测定法,探讨了在不同季节、地点和油茶林龄条件下,间种花生对土壤性质及对油茶生长的影响。结果表明,间种花生能提高土壤脲酶活性和细菌、放线菌数量,同时提高土壤有机质、全氮、碱解氮、全钾含量以及土壤含水量和pH值,降低土壤温度。不同地点和季节对土壤养分的改善程度不同。间种花生对一年生油茶生长有抑制作用,但对三年生油茶生长具有促进作用。此外,间种花生能产生一定的经济效益。影响间种效果的主要因素按重要性排序为地点、季节和油茶林龄。具体来说,宁西油茶种植基地间种效果优于仁化油茶种植基地,春季间种效果优于秋季,而三年生油茶林间种效果优于一年生油茶林。To explore the feasibility of intercropping peanuts in Camellia oleifera forests,experiments were conducted at Camellia oleifera planting bases.Through forest survey method and indoor measurement method,the impacts of intercropping peanuts on soil properties and growth of Camellia oleifera were investigated under different seasons,locations and Camellia oleifera forest ages.The results showed that intercropping peanuts could enhance soil urease activity and the numbers of bacteria and actinomycetes,as well as soil organic matter content,total nitrogen content,alkali-hydrolyzable nitrogen content,total potassium content,soil moisture content and pH value.Meanwhile,it reduced soil temperature.The extent of improvement in soil nutrients varied across different locations and seasons.Intercropping peanuts inhibited the growth of one-year-old Camellia oleifera,but promoted the growth of three-year-old Camellia oleifera.In addition,intercropping peanuts generated certain economic benefits.The main factors influencing the intercropping effect,ranked by importance,were location,season,and Camellia oleifera forest age.Specifically,the intercropping effect in Ningxi Camellia oleifera planting base was better than that in Renhua Camellia oleifera planting base,the effect in spring was better than that in autumn,and the intercropping effect in three-year-old Camellia oleifera forests was better than that in one-year-old forests.
